Yeah, usually the first thing I've notice is that when you RDP to a system and it kicks you back to the logon screen with no error, but no connect. You can go back to the server and log on just fine, and a reboot would clear the problem. On file servers we also get people that start to get strange "out of quota" messages, but then they can reconnect in a minute and things work.
Am I correct in reading this is a WS03 issue and not WS08? There is no newer ISCSI initiator (yet) for WS08. We finally have our new Equallogic PS6000s online with a new WS08 failover cluster using MPIO and I want to make sure this isn't going to affect us. -Bonnie From: Brian Desmond [mailto:br...@briandesmond.com] Sent: Tuesday, June 30, 2009 9:23 AM To: NT System Admin Issues Subject: RE: For those that use multipathing solutions with your servers NON Paged memory pool leak There are also issues with HP and probably the other major vendors in this space. There was a bug in the MS library they are all linked to. A lot of things can happen aside from that symptom below when you run out of nonpaged pool. A good indicator is if you see the SRV events (2019 or 202, I forget which one) saying you're out. Machines can hang, apps can stop working, etc. Thanks, Brian Desmond br...@briandesmond.com c - 312.731.3132 Active Directory, 4th Ed - http://www.briandesmond.com/ad4/ Microsoft MVP - https://mvp.support.microsoft.com/profile/Brian From: Ziots, Edward [mailto:ezi...@lifespan.org] Sent: Tuesday, June 30, 2009 6:34 AM To: NT System Admin Issues Subject: For those that use multipathing solutions with your servers NON Paged memory pool leak All, http://seer.entsupport.symantec.com/docs/317378.htm http://blogs.technet.com/andym/archive/2008/12/04/powerpath-5-2-and-mpio-causing-npp-leak.aspx The culprit in EMC land is the 5.2 and 5.2 SP1 PowerPath Drivers ( MPIO.sys of 1.22.3790.2358) and the EMCMPIO.sys of 5.2.1.6 (5.2 SP1) The fix: Move up to EMC multipath drivers Version 5.3 which will load Microsoft's MPIO.sys updated to 1.23.3790.2451 which seems for the time being to address the Non-Page Memory Pool leak, this was driving one of my Exchange 2003 SP2 2-node clusters insane over the last few months, it was discovered if the NON-Paged Memory counter you see on the Task manager gets about 106-108MB for a X86 32bit system, the http service for the Exchange Cluster will fail, and cause the Exchange group to fail because the resource is marked to affect the group.
